The present invention relates to new compounds and an object of the present invention is to provide compounds which exhibit estrogenic activity or aid in increasing the rate of growth in meat-producing animals, e.g., cattle, lamb and swine. The compounds of this invention are illustrated by the formula:

where R is hydrogen, substituted or unsubstituted alkyl e.g. lower alkyl such as methyl, pentyl etc., and acyl, e.g.,

lower saturated acyclic radicals such as acetyl and valeryl; Z is C=O, CHOH, or CHOR; and X is Where R is hydrogen, hydroxyl or N(R R is hy drogen, substituted or unsubstituted alkyl or aralkyl, e.g., of about 1 to 15 carbon atoms, particularly lower alkyl, such as methyl, ethyl, etc., or benzyl, or substituted or unsubstituted aryl, e.g., phenyl or bromophenyl; with the proviso that at least one R is hydroxyl.

The compounds of the present invention can be produced from the compound:

\ 4 on erro as hereinafter referred to as the fermentation estrogenic substanc (F.E.S.) by reaction with formic acid in the presence of a catalytic amount of perchloric acid and hydrolysis of the resulting formats to add a hydroxyl at the ethylenic double bond. F.E.S. epoxides are produced by reaction of an F .E.S. ether with perbenzoic, monoperphthalic or peracetic acids and F.E.S. glycols can be produced either directly from a F.E.S. ether with hydrogen peroxide or indirectly by hydrolysis of an epoxide. F.E.S. epoxides are intermediates in the production of RES. amino alcohols which are formed by reaction of an epoxide with ammonia or an amine. In general, amine of the formula NH(R where R has the above designated meaning are suitable.

It is desirable, if not necessary, to protect the hydroxyl groups against undesirable side reactions before the reactions described above. This can be accomplished by converting the hydroxyl groups to ester groups, e.g., acetyl groups, as taught in US. Patent 3,239,342, and subsequently removing the masking group to regenerate the hydroxyl group. The hydroxyl group can be regenerated from, for example, a diacetate by hydrolysis by refluxing in an aqueous sodium bicarbonate solution containing ethanol to increase solubility. The compounds of the present invention where Z is CHOH can be prepared from compounds described in US. Patent 3,239,348 and Where Z is CHOR can be prepared from the compounds described in US. Patent 3,239,356. When Z is CHOH or CHOR, the carbon atom is an asymmetric carbon atom.

The compounds can be administered to animals by any suitable method including oral and parenteral administra tions. For example, the compound can be blended with ordinary feed containing nutritional values in an amount sufficient to produce the desired rate of growth and can thus be fed directly to the animals, or the compound can be suspended in a suitable injection suspension medium such as peanut oil and injected parenterally. The amount of compound fed to an animal, of course, varies depending upon the animal, desired rate of growth and the like.

When the new compounds are to be administered in feeds, an animal feed composition may be prepared containing the usual nutritionally-balanced quantities of carbohydrate, proteins, vitamins and minerals, together with the compound of the present invention. Some of these usual dietary elements are grains, such as ground grain and grain by-products; animal protein substances, such as those found in fish meal and meat scraps, vegetable proteins like soybean oil meal or peanut oil meal; vitaminaceous materials, e.g., vitamin A and D mixtures; riboflavin supplements and other vitamin B complex members; and bone meal and limestone to provide minerals. A type conventional feed material for use with cattle includes alfalfa hay and ground corn cobs together with supplementary vitaminaceous substances if desired. The following examples illustrate the invention.
